As seen in FIG. 15, the controller 34 enters the pairing mode when theswitch SW1 is pressed in the control mode of the bicycle electric device14. The telescopic controller 73 enters the pairing signal transmissionmode when the seatpost switch SW2 is pressed in the control mode of thebicycle electric seatpost assembly SP. The telescopic controller 173enters the pairing signal transmission mode when the suspension switchSW3 is pressed in the control mode of the bicycle electric suspensionFS. The first operating controller 24B enters the pairing signaltransmission mode when the first function switch 24D is pressed in thecontrol mode of the first operating device 24. The second operatingcontroller 26B enters the pairing signal transmission mode when thesecond function switch 26D is pressed in the control mode of the secondoperating device 26. In the pairing mode and the paring signaltransmission mode, for example, the indicators 44, 80, 24E, and 26Eslowly blink.

The telescopic controller 73 periodically transmits pairing signals PS21including the first identification information ID21 of the bicycleelectric seatpost assembly SP in the pairing signal transmission mode ofthe bicycle electric seatpost assembly SP. The telescopic controller 173periodically transmits pairing signals PS22 including the secondidentification information ID22 of the bicycle electric suspension FS inthe pairing signal transmission mode of the bicycle electric suspensionFS. The first operating controller 24B periodically transmits pairingsignals PS11 including the identification information ID11 of the firstoperating device 24 in the pairing signal transmission mode of the firstoperating device 24. The second operating controller 26B periodicallytransmits pairing signals PS12 including the identification informationID12 of the second operating device 26 in the pairing signaltransmission mode of the second operating device 26.

The controller 34 wirelessly receives the pairing signals PS21, PS22,PS11, and PS12 wirelessly transmitted from the telescopic controller 73,the telescopic controller 173, the first operating controller 24B, andthe second operating controller 26B. The controller 34 extracts thefirst identification information ID21, the second identificationinformation ID22, the identification information ID11, and theidentification information ID12 from the pairing signals PS21, PS22,PS11, and PS12. The controller 34 compares the first identificationinformation ID21, the second identification information ID22, theidentification information ID11, and the identification information ID12with the available device information AD1. The available deviceinformation AD1 includes a value indicative of the seatpost such as thebicycle electric seatpost assembly SP, a value indicative of thesuspension such as the bicycle electric suspension FS, a valueindicative of the right-hand side sifter such as the first operatingdevice 24, and a value indicative of the left-hand side shifter such asthe second operating device 26. Thus, the controller 34 stores the firstidentification information ID21, the second identification informationID22, the identification information ID11, and the identificationinformation ID12 in the memory 34B. In the control mode, the controller34 recognizes a wireless signal transmitted from a device paired withthe controller 34 based on the first identification information ID21,the second identification information ID22, the identificationinformation ID11, and the identification information ID12 stored in thememory 34B. However, the controller 34 does not respond to otherwireless signals transmitted from other devices. For example, theindicator 44 quickly blinks when the pairing succeeded.

The controller 34 wirelessly transmits a pairing completion signal PCSindicative of completion of the pairing to the bicycle electric seatpostassembly SP, the bicycle electric suspension FS, the first operatingdevice 24, and the second operating device 26. The telescopic controller73, the first operating controller 24B, and the second operatingcontroller 26B wirelessly receive the pairing completion signal PCS andrecognize that the pairing succeeded. For example, the indicators 80,180, 24E, and 26E quickly blinks after reception of the pairingcompletion signal PCS.

The controller 34 returns to the control mode when a time T1 is elapsedfrom sending of the pairing completion signal PCS. The telescopiccontroller 73 returns to the control mode after the specific time whenthe time T1 is elapsed after the telescopic controller 73 wirelesslyreceives the pairing completion signal PCS. The telescopic controller173 returns to the control mode from the paring signal transmission modeafter the specific time when the time T1 is elapsed after the telescopiccontroller 173 wirelessly receives the pairing completion signal PCS.The first operating controller 24B returns to the control mode from theparing signal transmission mode when the time T1 is elapsed after thefirst operating controller 24B wirelessly receives the pairingcompletion signal PCS. The second operating controller 26B returns tothe control mode from the paring signal transmission mode when the timeT1 is elapsed after the second operating controller 26B wirelesslyreceives the pairing completion signal PCS. For example, each of theindicators 44, 80, 180, 24E, and 26E turns off when the mode is switchedfrom the pairing mode and the paring signal transmission mode to thecontrol mode.

The controller 34 can be configured to keep the pairing mode for apreset time (e.g., 60 seconds) and to return to the control mode whenthe preset time is elapsed from a start of the pairing mode.Furthermore, the controller 34 can be configured to keep the pairingmode until the switch SW1 is pressed again. The same modifications canbe applied to at least one of the telescopic controllers 73 and 173.

In the control mode after the pairing, the controller 34 controls thebicycle electric device 14 and other bicycle components based on awireless signal including the first identification information ID21, awireless signal including the second identification information ID22, awireless signal including the identification information ID11, and awireless signal including the identification information ID12.

The controller 34 can be configured to wirelessly transmit theidentification information ID3 of the bicycle electric device 14 in thepairing mode. In such an embodiment, the telescopic controller 73 can beconfigured to wirelessly receive identification information such as theidentification information ID3 in the pairing signal transmission mode.The telescopic controller 73 can have a pairing mode which is differentfrom the pairing signal transmission mode and in which the telescopiccontroller 73 wirelessly receives identification information such as theidentification information ID3. Similarly, the telescopic controller 173can be configured to wirelessly receive identification information suchas the identification information ID3 in the pairing signal transmissionmode. The telescopic controller 173 can have a pairing mode which isdifferent from the pairing signal transmission mode and in which thetelescopic controller 173 wirelessly receives identification informationsuch as the identification information ID3.

Second Embodiment

A bicycle wireless control system 212 in accordance with a secondembodiment will be described below referring to FIGS. 16 and 17. Thebicycle wireless control system 212 has the same structure and/orconfiguration as those of the bicycle wireless control system 12 exceptfor the bicycle electric device 14 and the bicycle electric operatingdevice 22. Thus, elements having substantially the same function asthose in the first embodiment will be numbered the same here, and willnot be described and/or illustrated again in detail here for the sake ofbrevity.

As seen in FIGS. 16 and 17, the bicycle wireless control system 212comprises a bicycle electric device 214, the at least one electrictelescopic apparatus 16, and a bicycle electric operating device 222. Acontroller 234 of the bicycle electric device 214 has substantially thesame configuration as that of the controller 34 of the bicycle electricdevice 14. For example, the controller 234 is configured to control theelectric actuator 28 to upshift in response to the first wireless signalWS11. The controller 234 is configured to control the electric actuator28 to downshift in response to the second wireless signal WS12.

In this embodiment, as seen in FIG. 17, the bicycle electric device 214and the at least one electric telescopic apparatus 16 synchronize inresponse to the operation signal WS1. The controller 234 is configuredto wirelessly transmit the control signal CS to the at least oneelectric telescopic apparatus 16 based on the operation signal WS1wirelessly transmitted from the bicycle electric operating device 222.The first electrical switch 24A and the second electrical switch 26A areused for operating the at least one electric telescopic apparatus 16(the bicycle electric seatpost assembly SP and the bicycle electricsuspension FS). Thus, the first additional electrical switch 24G and thesecond additional electrical switch 26G are omitted from the bicycleelectric operating device 222. Thus, the bicycle electric operatingdevice 222 does not transmit the telescopic operation signal WS2.

The first control signal CS1 is transmitted from the controller 234 tothe first electric telescopic apparatus SP based on the operation signalWS1. The second control signal CS2 is transmitted from the controller234 to the second electric telescopic apparatus FS based on theoperation signal WS1. In this embodiment, the controller 234 isconfigured to wirelessly transmit the first control signal CS1 to thebicycle electric seatpost assembly SP based on one of the first wirelesssignal WS11 and the second wireless signal WS12. The controller 234 isconfigured to wirelessly transmit the second control signal CS2 to thebicycle electric suspension FS based on one of the first wireless signalWS11 and the second wireless signal WS12.

In this embodiment, for example, the controller 234 is configured towirelessly transmit the first control signal CS1 to the bicycle electricseatpost assembly SP based on the second wireless signal WS12 and acurrent gear stage. The controller 234 controls the electric actuator 28to downshift and wirelessly transmits the first control signal CS1 tothe bicycle electric seatpost assembly SP in response to the secondwireless signal WS12 (the downshift operation signal) when the currentgear stage is within a specific gear range (e.g., from the second tosixth gear stages). The downshifting between the first and sixth gearstages is likely to occur when the bicycle runs on an upslope. Thus, therider can adjust the height of the saddle BC3 (e.g., lower the saddleBC3) while the bicycle runs on the upslope. Furthermore, the controller234 controls the electric actuator 28 to upshift and wirelesslytransmits the first control signal CS1 to the bicycle electric seatpostassembly SP in response to the first wireless signal WS11 (the upshiftoperation signal) when the current gear stage is within a specific gearrange (e.g., from the ninth to eleventh gear stages). The upshiftingbetween the ninth and twelfth gear stages is likely to occur when thebicycle runs on a downslope. Thus, the rider can adjust the height ofthe saddle BC3 (e.g., raise the saddle BC3) while the bicycle runs onthe downslope.

Furthermore, the controller 234 is configured to wirelessly transmit thesecond control signal CS2 to the bicycle electric suspension FS based onthe second wireless signal WS12, the current gear stage, and a currentlock position of the bicycle electric suspension FS. The controller 234controls the first electric actuator 28 to upshift or downshift andcontrols the second electric actuator 156 to keep the unlocked positionof the positioning structure 154 when the current gear stage changeswithin a specific gear range (e.g., between the seventh and twelfth gearstages). Thus, the controller 234 does not transmit the second controlsignal CS2 regardless of the first and second wireless signals WS11 andWS12 when the current gear stage changes between the seventh and twelfthgear stages in the unlocked state of the bicycle electric suspension FS.The controller 234 controls the first electric actuator 28 to upshift ordownshift and controls the second electric actuator 156 to keep thelockout position of the positioning structure 154 when the current gearstage changes within a specific gear range (e.g., between the first andsixth gear stages). Thus, the controller 234 does not transmit thesecond control signal CS2 regardless of the first and second wirelesssignals WS11 and WS12 when the current gear stage changes between thefirst and sixth gear stages in the lockout state of the bicycle electricsuspension FS.

The controller 234 controls the first electric actuator 156 to downshiftin response to the second wireless signal WS12 and controls the secondelectric actuator 156 to move the positioning structure 164 from theunlocked position to the lockout position in response to the secondcontrol signal CS2 when the current gear stage changes from the seventhgear stage to the sixth gear stage. The controller 234 controls thefirst electric actuator 156 to upshift in response to the first wirelesssignal WS11 and controls the second electric actuator 156 to move thepositioning structure 164 from the lockout position to the unlockedposition in response to the second control signal CS2 when the currentgear stage changes from the sixth gear stage to the seventh gear stage.Thus, shocks can be absorbed by the bicycle electric suspension FS whenthe bicycle runs on the downslope in the current gear stage is betweenthe first and sixth gear stages.

The controller 73 isconfigured to wirelessly transmit the control signal CS to the at leastone electric telescopic apparatus 316 based on the telescopic operationsignal WS2 wirelessly transmitted from the bicycle electric operatingdevice 322. The controller 73 is configured to wirelessly transmit thecontrol signal CS (e.g., the second control signal CS2) to the at leastone electric telescopic apparatus 316 based on the telescopic operationsignal WS2 (e.g., the second telescopic operation signal WS22)wirelessly transmitted from the bicycle electric operating device 322(e.g., the second operating device 26).

The switch SW2 is electrically connected to thecontroller 73 to set the controller 73 to the pairing mode based on theuser input IP2 received by the switch SW2. Thus, the bicycle electricsuspension FS is wirelessly operated through the bicycle electricseatpost assembly SP.

In a modification of this embodiment, the bicycle electric device 314can include the bicycle electric suspension FS instead of the bicycleelectric seatpost assembly SP, and the at least one electric telescopicapparatus 316 can include the bicycle electric seatpost assembly SPinstead of the bicycle electric suspension FS.
